I have a DMtech LCD model LV19XTM - the power adapter shows a green light until it is plugged into the back of the TV then the light goes off and no power is getting to the TV - is this an adaptor problem or a fuse problem in the TV ? the solution provided on the website is not good enuf..!

You have an intermittent situation, the bane of all DIYers and normal repair people. Till it goes completely you might just want to check out the power supply of unit.

The FBT side circuit should be troubleshooted, Contact any experienced service technician. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

Do you still have the tv?

im having the same problem email me if you find solution ty.... [email protected]

is this the original power adapter or a new one. If it's a new or different power adapter, it could be the plug configuration on the new power adapter is different, as i had the same problem, but was able to fix it

Here is DMtech download page. If your model is not there , contact them to get the manual.

You might want to try a HASU05F. They are the same voltage, current, and connector and run cooler.

I have DMtech 20" with intergrated DVD and had the same problem- blue light lit on power switch but no response on power up.
I noticed that when the power cord was unplugged from the back of the TV the green LED on the power supply would brighten and consequently dim when plugged back in. Sometimes the blue light on the power switch would strobe very quickly but you had to look carfully for this.
I repeatedly unplugged the DIN type power plug from the back of the TV untill the green light on the power supply stayed a constant bright and there was no strobing on the blue light on the front of the TV, when I powered the TV on at this point the button worked again and the tv powered up with the silly tune then life in the screen. I did have to do this a good few times (I'm tenacious) but it did work!!!!!
Hope this helps someone else, cheers.

I would change the battey, if its not the battery i would place the media player on top
of some paper, stand back and admire your new paper weight.

power adapter is failing, get a different one and see.
